TYPEWRITING MACHINE.

Application filed .Tune 3,

To all whom t may concern: f

Be it known that I, Grenen A. SEIB, citizen of the United States, and resident of Ilion, lin the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

Yly invention relates to typewriting machines and more particularly to the type actions thereof.

In typewriting machines wherein the piv oted type bars are mounted in a segmentally arranged series, it has been found difficult to provide sufficient room in which to mount the requisite number of type bars and yet provide suiiicient room between them in the basket, so that in operation conflict between adjacent bars may be avoided. This is particularly true where the entire series 0f bals are mounted side by side with their pivotal centers in a single arc or plane, as for eX- ample where the type bars are mounted in guide slots of a segment to turn on a single pivot wire, with all parts of the latter dis-V posed in the same plane.

The main object of my present invention is to provide simple and eflicient means by which these difiiculties may be overcome.

A further object of the invention is to enable the features of my invention to be incorporated in existing forms of typewriting machines without material modification' thereof and without modifying the appearance 0f the machine.

To the above and other ends which will hereinafter appear, my invention consistsin the features of construction, arrangements of parts and combinations ofl devices set forth in the following specificati-on and particularly pointed out 'in the appended claims.I

In the accompanying drawingswherein like reference characters indicate correspending parts in the various views,

Figure 1 is a fragmentary fore and aft vertical sectional view of a typewriting ma'- chinc embodying my invention.

Figure 2 is a detail fragmentary front elevation of a portion of the same.

Figures 3 and 4 are detail fragmentary plan views. partly in section, and showing two left-hand and two right-hand typel bars, respectively.

1921. Serial No. 474,700.

to the same scale as Fig. 6 and showing some of the slots at the right-hand side of the segment and the type bars mounted therein.

I have shown my invention in the present instance embodied in an Improved No. l() Remington machine in which the invention may be incorpora-ted with but slight modification of the machine as it now exists.

should be understood however that the invention is not restricted to its embodiment in such machines. but may be employed in various styles of typewriting machines whereever found available.

ln the accompanying drawings, I have illustrated only s0 much of the machine as may be necessary to arrive at an understanding-of the invention.

Referring more particularlyto Figs. 1 and 2, it will be seen that the frame of the Imachine comprises a base a, corner posts b, and a top plate c, over which a carriage (not shown) travels from side to side of the machine and carries a plate-n d. A segmentally arranged series of upwardly andrea'rwardly striking sheet metal type bars are mounted in guide slots in a type barsegment c on 'a pivot wire f carried by the segment. The anc-shaped pivot wire is disposed in an upright plane', and all parts thereof are arranged at a uniform distance from the point of convergence of the type bars. From an inspection of Fig. 2, it will be seen that the distance between adjacent slots in the segment gradually increases from the center to the sides of the system. Each type bar moves from its segmental type rest g to the common printing point through about 90. In moving to the printing position each type bar enters between opposite jaws 0f the usual type bar center guide h secured t0 the segment e. The type bars may be' actuated by any suitable means, those shown in the present instance comprising spring returned key levers z' and bell crank sub-levers j. Each key lever is fulcrumed on a bar la fixed to the base of the machine and is pivoted at Z to the: associated sub-lever j. Each sub-lever is pivoted on a pivot wire m carried by a cross bar n fixed to the base 0f the machine. The upper end of each sub-lever carries a headed pin o which enters a slot p in the heel of the companion type bar. A segmental universal bar g supported for backward and forward movements on the segments is actuated by contacts 7 on the type bars. A rearward movement of the universal bar g transmits movement through arms s on said universal bar to arms t on a roc-k shaft u, and from a centrally disposed arm c; on the rock shaft to a link fw to actuate the carriage escape# ment, as disclosed in the patent to @scar lVoodward, No. 1,342,489, dated June 8, 1920.

The parts thus far described are the same as those employed in the Improved No. 10 Remington machine. In said machine, however, the guide slots in the type bar segment are all cut in radial planes which correspond to the radial planes of movement of the body portions of the type bars, all otl` said planes radiating from a common point of convergence of the type bars.

' In accordance with my present invention I propose t/omaintain the gradually increased spacing 0f the slots from the center to the sides of the system, but tg cut the guide slots, or some of them, in non-radial planes and to bend the body portion of each bar, thus mounted, laterally of the plane of its slot. rlhe result of this is that the body portion of each of said bars thus mounted, will not move in the plane of movement of its heel,

but will converge at a common center andl the laterally bent body portions of the type bars will fan upwardly when at rest in the basket as will hereinafter more clearlyapf pear.

ent instance, andbin accordance with the specific showing of its embodiment disclosed herein, it is intended that all of the fortytwo type bars shall be mounted in non-radial slots as specified, although only a few of the type bars are illustrated to simplify hand terminal type bar designated bythe numeral 42. The forty-two corresponding guide slots, counting from left to right, o1' the lines indicating the planes in which said slots are cut, are designated respectively by In carrying out my invention in the presthe reference numerals 1 to 42.` Thus the numeral 1` indicates the left-hand terminal ten times actual size, the sheets should be:v

placed so that the lines 42, for exan'iple, on

both figures are in alignment and are sepa-L rated, so that the distance from the upper end of thev line 42 in Fig. 6 will be about thirty inches from the lower end of the line 42 in Fig. 7.

From these views it willbe understood that each of the guide slots at each side4 of the segment is cut in a non-radial pla-ne, each plane crossing the median line .fr ofthe segment at a y\ditl'erent point and at a different distance from and below the printing point, as. will hereinafter clearly appear. After each type bar mounted in place in its guide slot, it is bent laterally of the plane of saidslot, as indi'- cated at y/ in Fig. 2, so that the body portions of the type bars converge at a common point .e and all are properly received in the type guide z, and strike at a common printing center. As each type bar returns to and remains in a state of rest in the basket it assumes a different and higher posi-- when at rest, the bars are slightly fanncd in opposite directions from the center to the sides of the system, s0 that each type bar remains defiected slightly away from its adjacent bar, as indicated in Figs. 3 and 4. The type carrying ends of the terminal bars are therefore at a higher elevation in the basket than they would be if mounted in radial slots. It follows that more room is provided in the type rest or basket for the system of type bars, and that a` greater space is provided between each pair of adjacent bars to avoid the liability of conflict between them in their movement towards and from yThe particular layout of the slots in the present insta-nce is best indicated from a consideration of Figs. 6 and T read together in the manner' hereinbefore described. "It has been explamed that the guide slots` on -each side of' the median line ,r of the segment are cut 1n non-radial planes. cach plane crossing said line at a different point.

The plane ofeachterminal Slot 1 or 42 crosses the line :n at the lowest point or at ai point furthest removed from and below the printing point, whereas the planes of the remaining slots cross said line at successively higher points, or nearer to the print-y ing point, as the center of the system of type bars` is approached. It also will lbe understood that the planes of each pair of corresponding guide slots at opposite sides of the segment, as 1 and 42 for example, intersect or converge atthe median line .c of the segment, and that the pointof intersection or convergence of the planes of each pair of corresponding slots differs` from that of every other pair of corresponding slots. It will be seen, moreover, that some of the planes indicated by the lines 1 to 21 converge at the left of the median line ai, or at that side of the line x where the corresponding slots are located. In a like manner .some of the lines 22 to 42 converge at the right of the median line or at that side of n the line where the corresponding slots are located.

If we assume that the distance on the line w from the lowest point of convergence of the planes 1 and 42, to the highest point on the line a: where the planes 21 and 22 converge is 2.1 inches in Fig. 6, or .21 of an inch in a full-size machine, then the of-setor non-radial cutting of the guide slots in the manner indicated will result in giving .an additional space (over that ordinarily produced by the radial mounting of the bars) of .010 of an inch between type bars, or an additional space of .210 of an inch divided between twenty-one type bars at each side of the median line of `the segment, or a total additional space of .420 of an inch. Of

course the gures given above are merely illustrative and may be widely deviated from, as may also the number of type bars employed, forty-four bars being employed insome instances.` Moreover, while I have referred to each of the type bars at each.

side of the segment as being mounted in a non-radial plane, it may, in practice, be found suflicient to 'tbhus mount only some of the type bars, the oers being mounted or arranged in radial planes. For example, it may be found'to be unnecessary to mount some of the type bars near the center of the system in non-radial slots. Vhere such radial slots are cut say, for example, the two or more for the center bars of the system, the heel of each such bar will move in the same plane as the body portion thereof, the body portions of the bars andthe planes of their slots converging at the point a where the bars converge and where each bar is bent to properly enter the type guide, the latter point being indicated at a.

My invention as defined by some of the broader claims of the present case, 4is included with other devices in the constructions disclosed in my (7o-pending application, Sr. No. 176,768, filed June l1, 1921,

the claims of said co-pending application being restricted to features not disclosed herein. i

F rom the foregoing it will be understood that in the construction as shown and described in the present instance, each type bar may be said to comprise a heel or pivot end portion z2 included between the bend 1/ and the rear end of the bar; a shank or body portion z3 between the bends y and a', and a stem a4 from the bend 2 to the free end of the bar, and on which stem the type block z5 is mounted. It will be seen, moreover, that the stem atis bent-laterally at an angle to the'body portion or shank z3, and that the latter has a slight lateral bend v/ ,between saidshank and the pivot end portion z2, so that each portlon z2, z3 and 24 lies in a different plane and each shank swings to al common center a, whereas its pivot end portion 22 swings in a plane divergent from said common center.

Various changes mav be made without departing from my invention.
